Terrible service - Hyundai Hatfield

The front window of my car was not working, when pushing the button the window does not close. I called Hyundai Hatfield to ask if I could bring the car to them to have a look. The lady who answered the phone was very friendly and spoke to a person in the workshop who advises that I need to bring the car in so that they can have a look to see what the problem is. She explained that in the event that they do not have the part that needs to be replaced in stock they will not be able to fix the car the same day which is understandable and not a problem. I asked if I can bring the car in around lunch time for them to have a look, she said that will be fine. I went to Hyundai Hatfield, one of the staff members advises that they cannot look at my car and that I must make a booking so that they can have a look. Seeing that I had to take leave from work to take the car there only to be offerd absolutely NO assistance what so ever is utterly pathetic. I had to book the car in on Tuesday and will have to take anoter day off from work as they close before I get home in the afternoon. I would like to make it very clear that I am very dissatisfied and frustrated with this, if I just took the car there without any prior arrangements I can completely understand that they could not assist but arrangements were made before 08:00 this morning.
